Robert Pike "This is is what I got in the mail... priority mail". It was in Robert Pike's mailbox 3 years ago, a legitimate-looking cashiers check, paying him to become a mystery shopper.

A similar offer was just recently sent via FedEx to a colleague's child, this time using a legitimate-looking, money order.

Justin Pritchard, scam expert, "They're very good at finding new ways to help you depart with your money" Justin Pritchard has written about scams like this for thebalance.com and says it generally includes depositing the check you're sent, then return a portion of it to the scammer.

Justin Pritchard, "Right, the main red flag on all of these is that you're sending money! In almost every case you're supposed to be receiving money, but somehow they convince you to send money and there very good at that"

Via Skype from Colorado, Pritchard says it can take days before your bank figures out the documents are bogus, which is why you should slow down.

Justin Pritchard, "You let that money sit in your account and in fact go ahead and contact the bank, that's a great idea just to get in touch and say hey this is a deposit that i'm not a hundred percent sure about"

Robert Pike didn't fall for it and neither did our colleague especially after we texted the scammer at the number he provided in the cover letter that came with that phony money order.
